From birth, the intestinal flora of your infant appears and develops. What is his role ? What can be done to preserve these indispensable microbes?
What is the intestinal flora composed of?
- Bacteria, which appear in a very specific pattern. Enterobacteria are the first to colonize the digestive tract within 24 to 48 hours after birth. They will create a poor oxygen environment that characterizes the mature digestive tract and allow the development of other bacteria (bacteroids, bifidobacteria, etc.), which are then added, for example, streptococci and lactobacilli.
- At the end of the first week of life, billions of bacteria are present in the stool of the newborn. The more it grows, the more its intestinal flora becomes complex and diversified. At the age of 2, she is close to that of the adult.
Why is it essential?
- It contributes to the proper functioning of the digestive system and the renewal of mucus, protective cells of the intestine. It also plays a role in nutrition, by breaking down large food molecules that are difficult to assimilate. It also plays an essential role as a barrier against pathogenic bacteria.
- Other important function : the intestinal microflora participates in the formation of the immune system of the child.
